The root cause for piping vibration can be one or many of the following: Mechanically-induced vibration Fluctuating Line Pressure (LP) Flow-induced by variations in Kinetic Pressure (KP) Pulsation-driven, i.e. excited by propagating waves in the pipe system Figure 1. Pressure, Line Pressure, Pulsation and %LP. %LP matters for the generation of shock waves from wave steepening, a topic treated elsewhere in this Learn More section. (Click on figure to expand) Mechanically-induced vibration tends to be the largest near a machine or perhaps, externally-induced vibration transmitted e.g. via a...
